i CARTON Specication of Letters Patent.

Application filed May'12, 1913. Serial No. 766,967.

To all whom z't may concern Be it known that I, PETER BERKEY, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Cartons, and declare the -following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to cellular cartons, and particularly to cartons' which are adapted to be supplied in a collapsed condition and to be opened or expanded when and as required.

In a well known type of carton all of the parts, including the transverse partitions, excepting a longitudinal dividing partition, are permanently connected together, and the transverse partitions are moved into and held in their proper positions by means of the separable longitudinal partition.

The principal object of the present invention is so to improve the construction of the type of carton last described that the longitudinal partition is securely locked in place by the simple act of pressing it down on the transverse partitions.

A further object of my invention is to provide a simple, novel and eliicient means for cushioning the contents of a carton so that they will not be jarred when the carton is set down or during the transportation of the carton.

The lvarious features of novelty whereby my invention v is characterized will herein after be pointed out with particularity in the claim; but, for a full understanding of my invention and of its objects and advan tages, reference may be had to the following detailed description taken in connection with the accompanying drawing, wherein:

Figure 1 is a perspective View of a carton arranged in accordance with a preferred form of my invention, opened for use; Fig. 2 is a perspective viewof the carton in the process of having its partitions put in proper working positions; and Fig. 3 is a transverse section on a reduced scale.

- Referring to the drawing, 1, 2 and 3 represent respectively the front, back and bottom of a carton and,` 4, the cover of the carton.

5 is a locking strip on the free end of the cover. e 6, 6 are transverse partitions of any desired number, connected at their upper front corners to the front side of the carton and at thelr upper' rear corners to a longitudinal strip, 8, which is fastened to the back side of the carton. This arrangement permits the transverse partitions to be swung from a plane parallel with the bottom of the carton into separate parallel planes at right angles to the bottom; the first position being that which the partitions occupy when the carton is collapsed and the second position being that when the carton is opened and made ready for use Each of the transverse partitions has in the upper edge thereof midway between its ends' a notch or slot, 9 which extends through approximately hali the width'or depth of the-partition.

10 is a 4longitudinal partition having la length approximately equal to the length of the front and back sides and having in its lower edge a series of notches or slots 11, 11 spaced apart at distances equal to the distances between the transverse partitions and of a depth suiiicient to permit the lower edge of the longitudinalpartition to rest upon the bottom of the box when the parts are assembled as shown in Fig. 1. The slots in the longitudinal partition are made wider than the thickness of the material of the transverse partitions and increase in width from the top toward the bottom. The rear edge of eachof the slots in the longitudinal partitions is preferably made straight and inclined to the bottom edge of the partition. lVith this arrangement, `when the carton is opened and the transverse partitions still lie parallel with the bottom of the carton as shown on the left hand end of Fig. 2, one end of the longitudinal partition is engaged with the corresponding transverse partition, with the other end of the longitudinal partition held raised, and the longitudinal partition is then gradually pressed down so as to engage it progressively with the entire series of transverse partitions and swing these partitions one after another into their upright positions.

In the arrangement 'just described, the longitudinal partition sometimes drops out unless the cartonis carefully handled until filled and the cover closed. In accordance with one feature of my invention, I provide means for quickly and easily locking the longitudinal partition against accidental displacement, without requiring any operations or manipulations in addition to those necessary to place the carton in a working condition as heretofore explained. This is accomplished by forming on the front edge of one of the slots in the longitudinal partition a tooth, 12, which extends some distance across the slot, the rear end of the slot being concave, as at 13, to provide a clearance space adjacent to the tooth. In the transverse partition corresponding to the slot in which the tooth 12 is located I form a small hole, 14, below the slot 9 and i'n a position to be engaged by the tooth when the longitudinal partition is pressed down. With this arrangement, the pressing down of the transverse partitions is accomplished in just the same way as where there is no tooth, but the tooth is forced through the opening 14 in the corresponding transverse partition and serves to interlock that partition withv the longitudinal partition and therefore prevents the latter partition from being accidentally displaced.

In accordance with another feature of my invention, I emboss the bottom of the carton, as indicated at 15, 15 \so as to provide a raised seat in each one of the compartments formed between the longitudinal partition and the transverse partitions. The contents of the carton therefore rest on these amazes rais'ed seats and are yieldingly supported above the surface on which` the bottom of the carton niay be resting, so that the contents of the carton are effectively cushioned and the contents will be protected against shocks and jars.

I claim: y

In a carton, a series .of transverse partitions connected at their upper corners only to two opposed sides of the carton so as to permit the partitions to swing from positions in a common horizontal plane to positions in separated parallel vertical planes, slots extending part Way through the aforesaid partition from the upper edges thereof, a longitudinal partition having in its lower edges a series of inclined flaring slots adapted to receive the portions of the transverse Vpartitions lying below the slots in the latter partitions, said longitudinal partition having a single toothor -projection located about. midway between its ends and projecting part way across one of the slots in the longitudinal partition, and the corresponding transverse partition having below the slot therein a hole for receiving the tooth or projection. In testimony whereof, I sign this speciiication in the presence of two witnesses. PETER BERKEY. IVitnesses WM. F. FREUDENREICH, RUTH E. ZETTERVALL.
